8:00 PM NOVA – “Extreme Cave Diving”
Follow the charismatic Dr. Kenny Broad as he dives into Blue Holes — underwater caves that formed during the last ice age when sea level was nearly 400 feet below what it is today. They are Earth’s least explored and perhaps most dangerous frontiers. With an interdisciplinary team of climatologists, paleontologists and anthropologists, Broad investigates the hidden history of Earth’s climate as revealed by finds in this spectacularly beautiful “alternate universe.”

9:00 PM Cave People of the Himalayas
An archaeologist dangles from a rope spanning a cliff 800-feet tall. A dark cave opening looms 700-feet down and the only way inside is to rappel down from above. Dr. Mark Aldenerfer, self-proclaimed landlubber, is not happy performing aerial acrobatics, but he’s doing it for science, while seven-time Everest climber, Pete Athans, belays him. They’re on a mission, set within the world’s highest mountains, to find ancient mummies and uncover secrets that have been hidden in these cliff-top graves for thousands of years.
